Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of anti-loosening devices for anesthesia tubes, and particularly to a tracheal intubation fixation and anti-detachment device commonly used in anesthesia. Background Art
[0002] Tracheal intubation is an effective method for establishing an artificial airway during clinical rescue of cardiac arrest and other critically ill patients. Tracheal intubation can also be used in anesthesia operations to deliver anesthetic gases through tracheal intubation. However, after tracheal intubation, good fixation must be carried out. Once tracheal intubation dislodges, it will cause secondary harm to the patient and may even prevent the patient from being fully anesthetized.
[0003] A tracheal intubation fixator can quickly, safely, and stably fix the tracheal intubation, significantly reducing the occurrence of accidental events such as tracheal intubation displacement and detachment. However, the inventor found that at the current stage, the connection positions of the two ends of the tracheal intubation fixator with the binding straps, as well as the positions in contact with the perioral tissues and the skin of the cheeks, do not have corresponding decompression measures, resulting in these relatively sharp parts being prone to damaging the patient's skin tissue. Moreover, due to the relatively smooth contact part between the current fixator and the anesthesia intubation, the fixation stability of the pipeline is insufficient, and medical staff often need to wrap non-woven fabric around the anesthesia intubation to increase friction. Summary of the Invention
[0004] In view of the defect that the traditional tracheal intubation fixator is prone to cause damage to facial or perioral skin and mucous membranes during the process of fixing the trachea in the above background art, a technical solution for a tracheal intubation fixation and anti-detachment device commonly used in anesthesia is provided.
[0005] It includes a support arc plate mechanism, elastic binding strap assemblies are fixedly connected to the left and right ends of the support arc plate mechanism, a facial skin anti-injury cushion layer is fixedly connected to the bottom arc surface of the support arc plate mechanism through an adhesive, and a tracheal biting anti-detachment mechanism is arranged in the middle area of the top arc surface of the support arc plate mechanism; The support arc plate mechanism includes a perioral arc-shaped cover plate, arc-shaped warping plates fixed at the left and right ends of the perioral arc-shaped cover plate, and fixing seats fixed at the front and rear positions on the upper surface of the perioral arc-shaped cover plate. An oval opening located above the mouth is arranged in the middle position inside the perioral arc-shaped cover plate; The tracheal biting anti-detachment mechanism includes two symmetrically arranged biting plates, a lead screw rotatably arranged on the outer side of the front biting plate, and 5-7 rubber arc-shaped sleeves embedded on the end faces of the biting plates close to each other. Guide rods are fixed on the mutually remote sides; Specifically, after the supporting arc plate mechanism is attached to the face, it is tied by the elastic binding belt assembly to make the perioral silicone pad fit with the perioral skin, and the cheek silicone pad fit with the cheek skin. At the same time, the perioral silicone pad and the cheek silicone pad discharge the internal air through the fine holes on themselves, which can play a buffering role while allowing themselves to have the ability to shrink and expand, greatly reducing the damage caused by direct contact between the perioral arc cover plate and the arc seesaw and the face. Then, turning the knob drives the screw to move inside the fixing seat, and under the guidance of the guide rods on both sides, the screw pushes the bite plates closer to each other, and the anesthesia pipeline can be placed arbitrarily between one of the rubber arc sleeves. The elasticity of the rubber arc sleeve wraps the anesthesia pipeline, which not only tightly bites the pipeline to maintain its stability, but also protects the anesthesia pipeline.
[0006] One end of the screw rod away from the bite plate passes through the interior of the front fixing seat, the left and right sides of the fixing seat are fixedly connected with fixing blocks, and one end of the guide rod away from the bite plate passes through the interior of the fixing block; The facial skin damage prevention pad layer includes a perioral silicone pad fixed to the middle area of the bottom surface of the perioral arc cover plate, and a cheek silicone pad fixed to the bottom surface of the arc seesaw plate; Specifically, after the bottom surface of the perioral arc cover plate contacts the perioral skin, the ends of the arc seesaw plate will be away from the cheeks and face due to its raised arc edge. At this time, the inner side of the left elastic band contacts the face and cheeks and is wrapped around the back of the head. The right elastic band is wrapped around the back of the head and superimposed on the outer surface of the left elastic band. The support arc plate mechanism is fixed at the mouth position of the face through the hooking and adhesion of the Velcro surface sticker and the Velcro surface sticker. At this time, because the corners of the arc seesaw plate and the edge of the perioral arc cover plate contact the facial tissue, the arc chamfers of the perioral arc cover plate and the arc seesaw plate corners can avoid the problem of too small stress area of local facial tissue. At the same time, the corners of the arc seesaw plate are wrapped by the silicone sleeve, which can also protect the facial skin.
[0007] The elastic binding belt assembly includes a left elastic belt and a right elastic belt, the outer surface of the left elastic belt is sewn with a Velcro patch, and the inner surface of the right elastic belt is sewn with a Velcro patch adhered to the Velcro patch.

[0029] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows: After the bottom surface of the perioral arc cover plate 11 contacts the perioral skin, the ends of the arc seesaw 14 will be away from the cheeks and face due to its raised arc edge. At this time, the inner side of the left elastic band 41 contacts the face and cheeks and is wrapped around the back of the head. The right elastic band 42 is wrapped around the back of the head and superimposed on the outer surface of the left elastic band 41. The support arc plate mechanism 1 is fixed to the mouth position of the face through the hooking and adhesion of the Velcro surface sticker 43 and the Velcro surface sticker 44. At this time, because the corners of the arc seesaw 14 and the edge of the perioral arc cover plate 11 contact the facial tissue, the arc chamfering of the corners of the perioral arc cover plate 11 and the arc seesaw 14 can avoid the problem of too small stress area of the local facial tissue.

At the same time, the perioral silicone pad 31 and the buccal silicone pad 32 discharge the internal air through the fine holes on themselves, which can play a buffering role and enable themselves to have the ability of contraction and expansion, greatly reducing the damage caused by the direct contact between the perioral arc-shaped cover plate 11 and the arc-shaped rocker 14 and the face. Subsequently, the knob 24 is rotated to drive the lead screw 25 to move inside the fixed seat 13. Under the guiding action of the guiding rods 22 on both sides, the lead screw 25 pushes the occlusal plates 27 to approach each other, and the anesthesia pipeline can be placed arbitrarily between one of the rubber arc-shaped sleeves 26. The elastic rubber arc-shaped sleeve 26 wraps the anesthesia pipeline, which not only tightly bites the pipeline to maintain its stability, but also plays a protective role for the anesthesia pipeline.
